Feeling agoraphobic

I haven't posted in a couple days for a couple of reasons. One is that I've been struggling with a migraine on and off for the past couple weeks and second, I've been feeling crappy because of it. I'm having a hard time trying to write because my head feels stuffy and I can't think straight. I thought I would try my hardest to sit down and write how I'm feeling right now because I'm sure other agoraphobics can relate. In order for me to function properly it's almost as if the stars have to be properly aligned:) I have to be well rested, fed and without sickness or pain. If just one of those things is off.... I'm off. I become very agoraphobic when things are "off". So, since I've had a headache for the last couple days and it's not responding to Advil, I haven't left my house. I just can't imagine trying to deal with my anxiety when all I can feel is the pain in my head. In my mind it's a combination for failure and I don't even attempt it. When Rick gets home from work tonight, we're supposed to go to Walgreens. I'm totally freaking out right now. I just don't know how I'm going to do it. I feel so disoriented and out of body right now. These are the times that all the irrational thoughts run rampant. I have the feeling of impending doom. Like something bad is going to happen at any minute. I wonder if something is wrong with me. Rationally I know that it's my anxiety making these assumptions but it's hard to think or believe otherwise when I feel like shit!
